It was 6:33 a.m. on a Thursday when the first spark hit the dry grass near Pulga. Most people in Paradise were still pouring their first cup of coffee or hitting the snooze button, totally unaware that the ridge above them was already beginning to burn. By the time the sun was fully up, the Camp Fire had become a monster. It wasn't just a fire; it was a firestorm that moved at the speed of a football field every second. People always ask about what started the paradise fire like it was some freak accident of nature, but the reality is much more frustrating and, frankly, a lot more bureaucratic than most realize. It wasn't a lightning strike. It wasn't a campfire left burning by a hiker.
It was a small, rusted piece of hardware on a high-voltage transmission tower.
The C-Hook That Changed Everything
If you want to understand what started the paradise fire, you have to look at a tiny, specific part called a "C-hook." This wasn't a high-tech failure. It was old-school metal-on-metal wear and tear. A PG&E (Pacific Gas and Electric) transmission line known as the Caribou-Palermo 115 kV line had been standing since the early 20th century. One of those towers, Tower 27/222, held up a heavy line using a series of hooks and insulators.
Over decades—literally a hundred years—the wind caused these lines to sway. That swaying created friction. The metal hook slowly ground away, bit by bit, year after year, until it was thin as a dime. On the morning of November 8, 2018, that hook finally snapped.
The line dropped. It hit the metal tower. Sparks flew into the ultra-dry brush below. Because the humidity was in the single digits and the "Diablo winds" were screaming down the canyons at 50 miles per hour, those sparks didn't just smolder. They exploded. Within minutes, the fire had jumped the Feather River. Within an hour, it was knocking on the door of Concow and Paradise.
Why Didn't the Power Get Cut?
One of the biggest controversies regarding what started the paradise fire is why the power stayed on during such high-wind conditions. PG&E had a "Public Safety Power Shutoff" program, but it was rarely used back then. They were worried about the backlash of leaving people in the dark. They were worried about the logistics. On that morning, they saw the wind reports. They knew the risk was "extreme." Yet, the lines stayed energized.
Investigations by the California Public Utilities Commission (CPUC) later found that the company had skipped or delayed many inspections on those specific old towers. Some of the hardware hadn't been physically climbed and checked by a human in years. They relied on "ground-based" inspections—basically looking up with binoculars. You can't see a worn-down C-hook with binoculars from 100 feet below.
Beyond the Spark: The Climate Powder Keg
It’s easy to blame the hook, and legally, that’s where the fault lies. PG&E eventually pleaded guilty to 84 counts of involuntary manslaughter. But the spark is only half the story of what started the paradise fire. The other half is the environment it landed in.
Northern California hadn't seen a drop of significant rain in months. The "fuel moisture" levels—a fancy way of saying how much water is inside the trees and grass—were at historic lows. Usually, by November, the autumn rains have started. In 2018, they were late. This made the entire ridge a tinderbox. When that line hit the tower, it wasn't landing on green grass; it was landing on kiln-dried kindling.
The Topography Trap
Paradise was built on a ridge. That's part of its beauty, but it was also its curse. The town sat between deep canyons. These canyons act like chimneys. When a fire starts at the bottom or the side of a canyon, the wind sucks the flames upward, accelerating them. This is why the fire moved so fast that people had to abandon their cars and run. The geography turned a mechanical failure into a death trap.

Think about the sheer physics of it. Fire usually moves uphill. In Paradise, the wind pushed it laterally across the plateaus so fast that the traditional "evacuation zones" became useless. The fire was jumping over entire neighborhoods before the first responders could even set up a perimeter.
Accountability and the Aftermath
CAL FIRE investigators spent months combing through the debris near Pulga. They found the snapped hook. They found the wear marks. They documented everything. It became undeniable. This wasn't a mystery; it was a maintenance failure.
The legal fallout was massive.
- PG&E filed for bankruptcy in 2019 because of the liabilities from this and other fires.
- A multi-billion dollar settlement was reached for the victims, though many say it was never enough to replace what was lost.
- The company was forced to overhaul its entire inspection process, now using drones and high-res cameras to check every single bolt and hook.
It’s a bit late for the residents of Paradise, though. Many have moved back and started rebuilding, but the town is different now. The trees are gone. The "forest" feel is replaced by wide-open spaces and new construction built to much stricter fire codes.
What Most People Get Wrong About the Cause
Some people still think a transformer blew up. Others think it was a deliberate act of arson. Honestly, the truth is just more boring and sadder: it was a lack of grease and a lack of eyes on an old piece of metal. There’s a misconception that "wildfires are just a part of life in California." While true, the Camp Fire wasn't an "act of God." It was a man-made disaster enabled by a changing climate and aging infrastructure.
When we talk about what started the paradise fire, we have to talk about the "culture of maintenance." If you own a car for 100 years and never change the brakes, eventually you’re going to crash. PG&E was running a 100-year-old grid and hadn't done the deep-level maintenance required for the "new normal" of California's weather.
Hard Lessons for Homeowners
If you live in a WUI (Wildland-Urban Interface), the Paradise story is a warning. You can't control the power lines. You can't control the wind. But the fire didn't just burn through the woods; it hopped from house to house because of "ember cast."
Hot embers can fly miles ahead of the actual flames. They land in gutters full of pine needles. They get sucked into attic vents. Many of the homes in Paradise didn't burn because the forest was on fire; they burned because they were easy targets for embers.
Actionable Insights for Future Safety
Understanding what started the paradise fire is only useful if it helps us prevent the next one. We can't wait for utility companies to be perfect. If you live in a high-risk area, here is what actually matters based on the data from the Camp Fire:

- Vents are the Weak Point: Retrofit your home with ember-resistant vents (1/8th inch mesh or specialized flame-baffling vents). Most homes in Paradise burned from the inside out because embers got into the attic.
- The 0-5 Foot Zone: This is the "non-combustible" zone. Remove everything that can burn—mulch, wooden fences attached to the house, bushes—from the immediate five-foot perimeter of your home.
- Red Flag Awareness: When a Red Flag Warning is issued, it's not a suggestion. It means the conditions are exactly like they were on the morning of November 8, 2018. Have your "go bag" in the car before you go to bed.
- Advocate for Microgrids: Communities are now looking into microgrids that can be "islanded" or powered by local solar/batteries so the main high-voltage lines can be shut off during wind events without leaving the town in total darkness.
The story of the Camp Fire is a tragedy of "small things." A small hook, a small spark, a small delay in a phone call. But those small things added up to the deadliest wildfire in California history. By acknowledging the specific failures—both mechanical and systemic—we can at least try to make sure that the next time a piece of metal wears thin, it doesn't take an entire city with it.
Staying informed about your local utility's "Wildfire Mitigation Plan" (WMP) is actually a great way to stay safe. These are public documents. You can see exactly which lines in your area are being buried underground and which ones are still hanging on 100-year-old hooks. Knowledge is the only real defense we have left when the wind starts to pick up.

Next Steps for Safety:
- Check your local fire hazard severity zone via the CAL FIRE website.
- Inspect your roof and gutters for debris monthly during the dry season.
- Create a "Hardened Home" checklist focusing on the immediate five-foot perimeter.
- Ensure your neighborhood has a two-way communication system that doesn't rely solely on cell towers, which often fail during major fires.
